Application filed October 20,1902. Serial No. 128,046. (No model.)

To all whom it may concern;

Be it known that 1, ANTON PSOTA, residing at VVestpoint, in the countyof Coming and State of Nebraska, have invented certain use fulImprovements in Cultivators; and I do hereby declare thatthefollowingisafull,clear, and exact description ofthe invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, refer ence being had to the accompanying drawings, whichform a part of this specification.

This invention relates to a new and useful improvement in cultivators.

The object of my invention is to provide a cultivator so arranged thatthe two side shovels may be controlled by the operator, thecultivator-shovels being so arranged that they may be carried upward anddownward and laterally inward and outward.

In the accompanying drawings 1 have shown in Figure 1 a side elevationof a cultivator embodying my invention, while Fig. 2 shows a sectionalView, with portions removed, of the mechanism used in securing theshovel-beams to the head.

In carrying out the aim of my invention I provide a central bar A. Thisbar is curved at its rear end, as is shown at a; in Fig. 1, and isprovided D, secured by means of the usual fastening 20, as is usual incultivator construction.

. At the forward end this central bar A is provided with the pin 6, bymeans of which is secured the notched-ended holder 5, so that thisholder may be tilted upward, working upon the pivot Bevolubly heldwithin this holder 5 is a bolt 4, securing the strap 3, fixed to thesingletree 1, provided with the usual tughooks 2, so that a singleanimal may be secured to this cultivator. At a suitable point thiscentral bar A is provided with a U-shaped strap 1), which is slotted, sothat the central bar A passes through the same. This strap 1) acts as aholder for a transverse shaft 9, which is in the form of a large boltprovided with the nut 19, as is shown in Fig. 2, and this shaft 9 issecurely held and secured to the central bar A, so that the same cannotwork laterally, by means of this U- shaped strap 7). NVorking upon theshaft 5) and adjacent the U-shaped strap 1) are two collars 30 30,(shown in Fig. 2,) and these with a narrow cultivator-shovel collars 30support the saddle-blocks e and f, and tightly working against thesesaddleblocks 6 and f are the washers 1O 10. These saddle-blocks are eachprovided with a projecting pin, (marked 12, shown in dotted lines inFig. 1. i

The upper saddle-block e by means of its pin 12 is pivotally secured tothe shovelbeam head 13, provided with the forward-extending car 15, andsecured to the lower side of this head B by means of the pin 16 is thepivotally-held jaw 13, the head member 15 and jaw 13 being united bymeans of the bolt 14, secured by means of the nut 18, as is clearlyshown in Fig. 1.

Each head B is provided with a plurality of openings .2, so that theshovel-beams H may be adjustably secured to these heads. Theseshovel-beams H are each provided with the usual shovel 24, secured bymeans of the usual holder 23.

Secured to each shovel-beam H is a bolt 28, from which extends thehandle 27, provided with a supporting-bar 26, suitably perforated toadjustably receive an ordinary bolt 25, so that these supporting-bars 26may be secured to the shovel-beams.

Extending from the forward portion of the central bar A and secured tothe forward end of this bar by means of the pin 8 are the two spreadingbrace-bars (1, (shown in Figs. 1 and 2,) these brace-bars beingperforated at their rear ends, so that the shaft 9 will readily passthrough the same.

It will be remembered that the holder 5 was described as having its endnotched and the lower projecting end 5 of the holder 5 as adapted toride below the forward end of the brace-bars a, as is clearly shown inFig. 1, so that this holder5 may be carried upward upon the pivot-pin 6,but will not drop down farther than its contact with the brace-bars aallows, as is shown in Fig. 1. From this it will be seen that thesingletree 1 by means of the bolt 4: is permitted a pivotal motion in ahorizontal plane and the pin 6 permitting a pivotal movement in avertical plane. The shovel-beams are secured to the heads B by means ofthe bolts 17, as shown in Fig. 1.

The cultivator would be constructed as follows: The U-shaped strap 1)would first be properly secured to the central bar A and securely fixedby means of the bolt 0. The shaft 9, which, as has been described, is inthe form of a bolt, would next be passed through one of the brace-barsa, as the one upon the righthand side, as shown in Fig. 2, thencethrough a washer 10, then being provided with the collars 30,the shaftthen being passed through the U-shaped strap Z2. Upon the opposite sidewould next be secured a counterpart collar 30, then the counterpartwasher 10, the remaining brace-oar being passed through the end. of theshaft 9, when the nut 19 would be threaded on the end of the same, as isclearly disclosed in Fig. 2. The next step would be to secure the saddleblocks or bearings e and f to the collar and then by means of theirprojecting pins 12 13, the bolt 14 then being extended through the headand jaw to secure the bearings e and f to the collar 30.

Nowitis desired to construct this cultivator so that either the right orleft shovel may be carried inward or outward, upward or downward, as theoperator may desire. In order to providea proper tension, the nut 19 isnext adjusted so that the washers 1O securely bind against thesaddle-blocks e and f, which form bearings, as it were, and so thatthese saddle blocks or bearings are pinched or impinged between thewashers 10 and the U-shaped strap b, so that these hearings are heldunder frictional contact. According to this construction it will benoticed that in raising the shovel-beams H upward'or downward thesaddle-blocks e and f will rub against the washers 10 and against theU-shaped strap 1).

In carrying the shovel-beams H to the side the head 15 and jaw 13 mustrotate and pivot about the pins 12, and in order to regulate the tensionhere the nuts 18 are adjusted so a tight tension may he obtained bymeans of the nuts 19 and 18.

Now in going through the field the cultivator is carried by means of thecentral shovel 24, which works in the center of the furrow between theplants. The operator then carries the side shovels I) to the right orleft, as the conditions may require, and can also raise and lower theshovels, as they are permitted a vertical and lateral movement by virtueof the connections described.

secure the head 15 and jaw my said invention,

and desire to-secure by ward end of said bar, bearings secured to saidshaft permitting a movement in a vertical plane, heads secured to saidbearings permitting a pivotal movement in-a horizontal plane and ashovel-beam secured to each of said heads.

2. The combination in a cultivator with a central shovel-provided beam,ofa transverse shaft secured near the forward end of said beam, abearing secured to said shaft upon opposite sides of said beam to permita movement in a vertical plane, a head pivotally secured to each of saidbearings, permitting a pivotal movement in a horizontal plane,shovel-provided beams secured to each of said heads, operating handlesextending from each of said beams and means to connect said shovel-beamsto said central bar.

3. In a cultivator, the combination with a central shovel-provided beam,a singletree secured at the forward end of said beam, a shaft laterallysecured to said beam, bearings upon said shaft upon opposite sides ofsaid beam, heads pivotally secured to said bearings, shovel-beamsextending from said heads, a rod uniting said beams to regulate theirspread, handles secured to each shovelbeam and means to secure saidshovel-beams to said central beams, all arranged substantially as andfor the purpose set forth.

In testimony whereof I alfix my signature in presence of two witnesses.

ANTON PSOTA.
